SPECIFICATION forming part Of Letters Patent No. 672,991, dated April 80, 1901.

' Beitknbwn that I, SERGEY Drink SMQLi-l ANILKOFE, a citizen of the United States, residing at Washingto'n','-iu the District of Columbia, have invented new and useful Improvements in New High Explosives, of which the following is a specification.

I have discovered anew chemical compound for an explosive that is absolutely safe'to handle, whether in a liquid or soiid or powdered orgelatinous form, under all conditions of transportation, storage, oruse, and which will remain stable and entirely unaffected by hr at and cold, moisture, climate, and atmospheric changes, This explosive compound is composed of nitroglycerin, empyreumatic oil, (principally obtained from the distillation of -wood-ta'r,) and oil of mirbane in varying proportions, according to the strength of explo sive required. The empyreumatic oil which I prefer tg-psejs alight oilof wood-tar, some-. \\times kn wuss spirit of tar, (Oleumpicis Am e-i r i i The enplosive may be'ordinarily prepared in aboutthe proportions of the constituents named, as follows: nitroglycerin, seventy per :ent., by weight; empyreumatic oil, (oil of wood-tar,) fifteen per cent., by weight; oil of mix-bane, fifteen per cent., by weight. These proportions may, howevenbe varied as desired without affecting the compound except as todegree of explosive force. It is preferable to first mix together the empyreumatic oil and the oil of mirbane in desired quantities or proportions and then add this first mixture to a suitable proportion of nitroglycerin, all the ingredients to be then thoroughly mixed together.

In order to obtain a granulated explosive or to permit molding or shaping of the compound into desired forms, I may add to the above-named mixture of nitroglycerin, em-

Application filed December 30, 1899. Renewed September 15, 1900- Serlsl No. 30.188. (R0 sp imenspyreumatic oil, and oil of mirbane a suitable proportion of magnesia or granulated charcoal or wooCt-pulp or any appropriate substance or substances to give bulk and body to the compound and vary its consistence. This compound may be readily molded in Va.

rious forms, if desired, or it may be formedintoa sheet to be cut into strips or blocks. A small quantity of any suitable resin or gum substance may be added if a gelatinized explosive is desired.

This compound of nitroglycerin, empyrenmatic oil, and oil of mirbane can be prepared in such proportions as to give a very great explosive force and yet be handled with the most perfect safety under all circumstances attending its transportation, storage, and use, whether as a liquid or in the form of powder,

granules, gelatin, or in a more or less solid state. v

This explosive compound will not decompose hut will remain absolutely stable until used. It is not exploded .by friction, compression, or concussion; it is not affected by air, heat, or water; it will stand exposure to high temperatures without explosion or decomposition, and it will not freeze.

In using this compound it is be exploded by any fulminate, chlorate, or detonating explosive.

\Vhat I claim as my invention -is-- A new explosive compound composed oi ni troglycerin, empyreumetic oil and oil of hair bane, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
